Add single-thread.h header
This patch move the single-thread syscall optimization defintions from syscall-cancel.h to new header file single-thread.h and also move the cancellation definitions from pthreadP.h to syscall-cancel.h. The idea is just simplify the inclusion of both syscall-cancel.h and single-thread.h (without the requirement of including all pthreadP.h defintions). No semantic changes expected, checked on a build for all major ABIs. * nptl/pthreadP.h (CANCEL_ASYNC, CANCEL_RESET, LIBC_CANCEL_ASYNC, LIBC_CANCEL_RESET, __libc_enable_asynccancel, __libc_disable_asynccancel, __librt_enable_asynccancel, __libc_disable_asynccancel, __librt_enable_asynccancel, __librt_disable_asynccancel): Move to ... * sysdeps/unix/sysv/linux/sysdep-cancel.h: ... here. (SINGLE_THREAD_P, RTLD_SINGLE_THREAD_P): Move to ... * sysdeps/unix/sysv/linux/single-thread.h: ... here. * sysdeps/generic/single-thread.h: New file. * sysdeps/unix/sysdep.h: Include single-thread.h. * sysdeps/unix/sysv/linux/futex-internal.h: Include sysdep-cancel.h. * sysdeps/unix/sysv/linux/lowlevellock-futex.h: Likewise.
